Comments on NASA Debates Terraforming Mars
NASA will hold a formal debate on terraforming Mars tomorrow night at its third Astrobiology Science Conference. (Read
the complete story)
|"The biggest hinderance to an attempted terraforming of Mars is that Mars does not possess a geomagnetic sheild like the Earth's, which protects the planet's organisms and atmosphere from the solar wind. Any atmospheric production on Mars would certainly be a losing battle by constant exposure to the solar wind and large scale solar events that would bombard and strip away Martian atmosphere."

|"Terraforming Mars is our furure. Sure there are problems to overcome but none that are impossible to surmount. We need Mars sooner than later if for no other reason than a sanctuary for earth's declining, endangered species of plants and animals.
With crater domes to hold in an atmosphere, and in-the-crater-wall tunnelling for shelter units to cut exposure to cosmic rays and radiation of the surface, the first 500 or so years of Mars life can be geared to sustainable atmospheric greenhouse gases production.
To live in a location that wants and needs the greenhouse gasses on a continual basis to maintain the atmosphere would seem odd at first, but in order to first have a pressure of an atmosphere, there must be continual manufacturing of these gasses that escape into space because of the poor gravity field there...jj

|"Our planet's spacefaring experience is in infancy. We have yet to go to the first planet past our own. And already you feel qualified/emboldened to terraform another world? Surely, you jest!"
(Art Taylor 8/5/2005 6:31:45 PM)
|"they need to think about terraforming with the global population growing and doubling each year and our planet cant take much more of this and we need to think about living on the moon or in space or mars becouse either we will destroy our own world or we will die out with our planet but we dont half to we can change our destiny"

|"first is exploration, on any scale, to seek-out and identify life, if any, existing in It's natural Martian habitat. Then decide whether to hinder or wipe out that, if any, lifeform's existance for the proposition to solve our own comfort problem. The issues are here, the study is there."

|"It seems like is a little too late to stop now...mold spores carry "accidentally" to mars inside Russians and American proves is already growing all over Mars at geometrical rates and Mars atmospheric conditions (wind and dust storm) are spreading and feeding the phenomena.... "
(Fernando Sanchez 6/5/2008 7:52:20 AM)
|"Exploration is in human nature... we have explored all of our world, so why stop there when we can explore or possibly create a new planet for ourselves to live on? "

|"Mars lacking a magnetosphere increases the solar wind and cosmic radiation impact on any lifeforms on the surface. However, Luhmann and Russell observe that historic Mars had a more significant field, and probably still had a thin atmosphere. The presence (or lack) of a magnetic field would not preclude an atmosphere. Venus (like Mars) has almost no magnetosphere, but has a surface atmospheric pressure equivalent to ~1km of H2O. Gravitational force is a more significant factor. The decision to terraform Mars would constitute almost irreversible destruction of indigenous lifeforms. Humanity has done measurable damage to Earth's environment, we should carefully consider the consequences before impacting yet another planet."

|"The concept of reforming a magneto sphere around mars is of high interest to me, I see two possibilities, One an enormous pit would be mined down to the core, or efectively close, then a huge space based laser, equivelent to the friggin death star, would restart the core. Two we could crash something the size and composition of mercury into Mars turning the whole planet molten, and increasing the mass which would increase gravity, kyper belt objects and asteriods could be used also, That may take too long to cool, it seems any approach would take anywheres from several thousand to millions of years... Although tera forming n the laser thing might work, in concert to asteriod, n comet inpacts
The key would be reigniting the planetary core...

|"heres another thought, lets take our excess CO2 and SO2, scrub it and take it to mars for release when we are ready. Also nuclear smelters mining iron from rust sand, and O2 bi-product storage... I wonder is there any helium 3 in the sand on mars like on our moon?
(devildog420 10/20/2011 12:23:52 AM)
|"Now that's a creative idea! A bit expensive, energy-wise, but it solves problems on two planets. Unless you're a Martian, I suppose..."
(Bill Christensen 10/20/2011 6:16:11 AM)
|" The core,mantle and crust are similar to earth's, made of iron, nickel, but provide a weak magnetic field to the atmosphere. I am thinking some kind of man made strengthening to the magnetism of the core will have to be achieved, first, for the atmosphere to survive."
(Allan Smithy Jones 3/31/2012 7:11:28 PM)
|"We might need to go with vast 'bubbles' to hold in the atmosphere we need. The good news is that the structural requirements will be less than they would be on Earth."
